    Abstract. The Soviet, Russian and European normative methods for determining the base distance between cracks normal to the longitudinal axis of bent reinforced concrete elements are considered. The distance between normal cracks in bent reinforced concrete elements has a significant impact on the results of the crack resistance calculation. In addition, this characteristic can be used when determining the lengths of bar finite elements in problems of modeling structural reinforced concrete systems in a non-linear setting by dividing the actual dimensions of the elements into distances between normal cracks based on a linear calculation from the action of loads caused by the own weight of structures. Such an approach in determining the dimensions of finite elements of reinforced concrete bar structures can become the basis for the further development of nonlinear calculations by the finite element method. The analysis of prerequisites, assumptions and calculations results is carried out on the example of free-end reinforced concrete beam. Alternative directions for the development of methods for crack distance and crack width calculating of reinforced concrete bending elements are proposed.
    Keywords: reinforced concrete beams, crack formation, crack pitch, distance between cracks, relative distance between cracks, crack opening width
